IMPROVEMENT IN- BARREL-'PITCH'ING MACHINES.

Specification forming part of Letters Patent No. 171.672, dated January 4, 1876; application filed August 18, 1875.

To all whom it may concern:

Be it known that I, HENRY LEHMANN, of Cleveland, county of Guyahoga, State of Ohio, have invented a Barrel-Pitching Machine, of which the following is a specification:

This invention relates to an apparatus for pitching beer-barrels, or, in other words, coating the inside of barrels with pitch, in which there is employed a furnace, connected with a fan-blower, whereby the air-blast from the fan enters underneath the fire-grate of the furnace, and, passing up through the fire, injects with it a fine spray of melted pitch through the injection-tube at the top of the furnace into the barrel, said injecting-tube being provided with a movable air-box, perforated and adapted for use as a cooling-chamber, in connection with the barrels being pitched.

To enable others to fully understand my invention, I will proceed to describe the same in detail with the aid of the accompanying drawing, in which a Figure 1 is a side elevation of the abovementioned machine. Fig. 2 is a detached View of a single injection-pipe, Fig. 1 having a triple injector attached. Figs. 3 and 4 are face and rear views, respectively, of the airbox.

A is a bed or frame, having casters or rollcrs for convenience of easily transporting the machine. On one end of. this bed is erected a frame, which supports the shafts, gears, and

pulleys for propelling a fan, B, which rests von the'bed within said frame. At the other end of the bed is placed a furnace, 0, having a dumping--fire-grate, D, beneath which the end of the pipe from the fan-blower enters. To the top of the furnace is attached an outletpipe, E, to which may be attached a triple nozzle, F, which would lead into three barrels or kegs at one time, thus facilitating the work of pitching. I

In Fig. 2 is represented a single nozzle, having a box or sleeve, G, Figs. 2, 3, and 4, made double, to provide an air-space, and which is perforated for the circulation of air within it. It is designed to surround the nozzle at its entrance to the barrel, to insure against the HENRY LEHMANN.
